First Embodiment

Referring to FIG. 1 to FIG. 9 , a first embodiment of the presentdisclosure is provided. As shown in FIG. 1 to FIG. 6 , the presentembodiment provides a contact lens 100 that can be referred to as asmart contact lens. The contact lens 100 can be worn on an eye 200 of auser (as shown in FIG. 3 ) or can be embedded in the eye 200 (not shownin the drawings) according to design requirements.

Moreover, the contact lens 100 in the present embodiment can have acorrecting function for a refractive error that includes hyperopia,myopia, astigmatism, presbyopia, or astigmatism-presbyopia; or, thecontact lens 100 can be a makeup lens without the correcting function.

The contact lens 100 in the present embodiment includes a lens body 1and an embedded module 10 that is embedded in the lens body 1. Theembedded module 10 includes a front supporting ring 4, a rear supportingring 5 facing toward the front supporting ring 4, an electroniccomponent 2 sandwiched between the front supporting ring 4 and the rearsupporting ring 5, and a circuit structure 3 that is sandwiched betweenthe front supporting ring 4 and the rear supporting ring 5 and that iselectrically coupled to the electronic component 2, but the presentdisclosure is not limited thereto. For example, in other embodiments ofthe present disclosure not shown in the drawings, according to designrequirements, the embedded module 10 can include only the frontsupporting ring 4, the rear supporting ring 5, and the circuit structure3, and be provided without the electronic component 2. In addition, anyone of the front supporting ring 4 and the rear supporting ring 5 can beregard as a supporting body. The following description describes thestructural and connection relationship of each component of the contactlens 100.

The lens body 100 in the present embodiment is formed by solidifying ahydrogel (e.g., p-HEMA) or a silicone hydrogel, but the presentdisclosure is not limited thereto. The lens body 1 includes an opticalportion 11 and an annular wearing portion 12 that surrounds the opticalportion 11. The optical portion 11 can be formed with or without thecorrecting function for the refractive error according to designrequirements. It should be noted that the optical portion 11 of thepresent embodiment is provided without any component embedded therein,but the optical portion 11 can also be formed to have at least onecomponent embedded therein according to design requirements (e.g., whenthe contact lens 100 is applied to a digital zoom device) and is notlimited by the description of the present embodiment.

Moreover, the optical portion 11 defines a central axis L, and a centerof the optical portion 11 and a center of the annular wearing portion 12are located on the central axis L. The annular wearing portion 12 isconnected to an outer edge of the optical portion 11 and issubstantially in a circular ring shape, and the embedded module 10 isembedded in the annular wearing portion 12. In addition, a productionmanner relevant to the embedded module 10 embedded in the annularwearing portion 12 (or a manufacturing method of the contact lens 100)can be adjusted or changed according to design requirements, but thepresent disclosure is not limited thereto.

Specifically, the embedded module 10 is embedded in the annular wearingportion 12, and each of the front supporting ring 4 and the rearsupporting ring 5 surrounds (an outer side of) the optical portion 11and has a center located on the central axis L. The front supportingring 4 has a front curved surface 41 and a rear carrying surface 42, andthe rear supporting ring 5 has a rear curved surface 52 and a frontcarrying surface 51 that faces toward the rear carrying surface 42.

Furthermore, the electronic component 2 and the circuit structure 3 aresandwiched between the rear carrying surface 42 of the front supportingring 4 and the front carrying surface 51 of the rear supporting ring 5,such that the electronic component 2 and the circuit structure 3 can beentirely embedded in the annular wearing portion 12. In the presentembodiment, at least one of the front supporting ring 4 and the rearsupporting ring 5 overlaps an entirety of the electronic component 2 andan entirety of the circuit structure 3 (along the central axis L), butthe present disclosure is not limited thereto. Moreover, lateral sidesof the electronic component 2 and lateral sides of the circuit structure3 are gaplessly connected to the annular wearing portion 12 (e.g., alower eyelid region 122 described in the following description).

In addition, any one of the front supporting ring 4 and the rearsupporting ring 5 is made of an eye-friendly material that can be ahydrogel (e.g., p-HEMA) or a silicone hydrogel. The eye-friendlymaterial can allow the front supporting ring 4 and the rear supportingring 5 to preferably have properties (e.g., an oxygen permeability) thatis similar or substantially identical to properties of the lens body 1,and the eye-friendly material of any one of the front supporting ring 4and the rear supporting ring 5 can be different from that of and thelens body 1, but the present disclosure is not limited by the presentembodiment.

In summary, in the contact lens 100 provided by the present embodiment,the contact lens 100 is designed to have the front supporting ring 4 andthe rear supporting ring 5, which are made of the eye-friendly material,for clamping and pre-positioning the circuit structure 3 and theelectronic component 2 therebetween, thereby facilitating the highprecision positioning of the circuit structure 3 and the electroniccomponent 2 in the manufacturing process of the contact lens 100.Accordingly, the contact lens 100 can have a high conformity in massproduction.

Specifically, when the circuit structure 3 and the electronic component2 are disposed in a forming mold (not shown in the drawings),positioning structures of the forming mold abut against the frontsupporting ring 4 and the rear supporting ring 5 to precisely positionthe circuit structure 3 and the electronic component 2 to apredetermined position, such that a hydrogel or a silicone hydrogel isinjected into the forming mold to encapsulate the embedded module 10,and is solidified to form the lens body 1. After the contact lens 100 istaken out from the forming mold, parts of the front supporting ring 4and the rear supporting ring 5 abutting against the positioningstructures of the forming mold respectively form the front curvedsurface 41 and the rear curved surface 52.

Specifically, the annular wearing portion 12 has a layout region 121being C-shaped and a lower eyelid region 122 that is arranged betweentwo ends of the layout region 121. The electronic component 2 isembedded in the lower eyelid region 122 of the annular wearing portion12. When the contact lens 100 is worn on the eye 200, the lower eyelidregion 122 and the electronic component 2 are arranged inside of a lowereyelid 201 of the eye 200 that is less sensitive than another portion ofthe eye 200, thereby effectively reducing a foreign body sensation (FBS)of the user.

In other words, as shown in FIG. 2 to FIG. 6 , (surfaces of) the lensbody 1 includes a rear surface 1 b and a front surface 1 a that isarranged opposite to the rear surface 1 b. The rear curved surface 52 isflush with the rear surface 1 b of the lens body 1 so as to jointlyprovide (or have) a predetermined curvature for being worn on the eye200. In other words, the predetermined curvature is only relevant forallowing the contact lens 100 to be worn on (or smoothly attached to)the eye 200. In addition, the rear curved surface 52 of the rearsupporting ring 5 of and the rear surface 1 b of the lens body 1preferably have no slot (or no hole), but the present disclosure is notlimited thereto.

Moreover, the front surface 1 a has a viewable surface 11 acorresponding in position to the optical portion 11, and the frontcurved surface 41 of the front supporting ring 4 is flush with the frontsurface 1 a of the lens body 1 so as to jointly form a free curvedsurface 12 a that corresponds in position to the annular wearing portion12. The front curved surface 41 of the front supporting ring 4 is flushwith the front surface 1 a of the lens body 1 and preferably has no slot(or no hole) formed thereon, but the present disclosure is not limitedthereto. In other words, an outer surface of the contact lens 100 has noslot (or no hole). The viewable surface 11 a has a first curvaturerelevant to an optical design for correcting the refractive error; or,the first curvature of the viewable surface 11 a and the rear surface 1b can jointly form a structure with no diopter.

Specifically, the first curvature of the viewable surface 11 a isdifferent from a second curvature of the free curved surface 12 a, and athickness of the annular wearing portion 12 gradually increases in adirection toward the electronic component 2 (or the lower eyelid region122), but the present disclosure is not limited thereto. For example, inother embodiments of the present disclosure not shown in the drawings,the first curvature can be substantially equal to the second curvature,and the thickness of the annular wearing portion 12 is substantiallyuniform.

In other words, through the front supporting ring 4 and the rearsupporting ring 5, any position of the annular wearing portion 12 of thecontact lens 100 can be provided to have at least one of the electroniccomponent 2 embedded therein according to design requirements. Forexample, in other embodiments of the present disclosure not shown in thedrawings, two opposite sides of the annular wearing portion 12 in ahorizontal direction of the eye 200 can each be provided to have atleast one of the electronic component 2 embedded therein through thefront supporting ring 4 and the rear supporting ring 5, so that theannular wearing portion 12 has a largest thickness in the horizontaldirection and becomes gradually thinner in a vertical direction of theeye 200. Accordingly, the above arrangement of the contact lens 100 canenable the contact lens 100 to receive at least two of the electroniccomponents 2 and to reduce the FBS of the user.

In summary, the contact lens 100 of the present embodiment is providedwith the free curved surface 12 a arranged on the front surface 1 a ofthe lens body 1 and the front curved surface 41 of the front supportingring 4, so that a thickness of the layout region 121 does not need to bebased completely on (or be equal to) a thickness of the lower eyelidregion 122 for thinning the layout region 121. Accordingly, an oxygenpermeability of the layout region 121 can be effectively increased, andthe FBS of the contact lens 100 can be reduced (or improved).

In order to further increase the oxygen permeability of the layoutregion 121 and further reduce the FBS of the contact lens 100, thecontact lens 100 preferably has at least one of the technical featuresdisclosed in the following paragraphs by adjusting the second curvatureof the free curved surface 12 a, but the present disclosure is notlimited thereto.

The annular wearing portion 12 (and/or the embedded module 10) has alargest thickness Tmax located at a part of the annular wearing portion12 (e.g., the lower eyelid region 122) corresponding in position to theelectronic component 2, and also has a smallest thickness Tmin locatedat a part of the layout region 121 (e.g., a top part of the layoutregion 121 shown in FIG. 4 ) away from the lower eyelid region 122. Inother words, when the contact lens 100 is worn on the eye 200, the partof the annular wearing portion 12 (and/or the embedded module 10) of thecontact lens 100 having the largest thickness Tmax is located inside ofthe lower eyelid 201 of the eye 200, and the part of the annular wearingportion 12 (and/or the embedded module 10) of the contact lens 100having the smallest thickness Tmin is located inside of the upper eyelid202 of the eye 200. The largest thickness Tmax and the smallestthickness Tmin in the present embodiment respectively correspond inposition to the lower eyelid 201 and the upper eyelid 202 of the user,but the relationship between the thickness of the contact lens 100 andthe eyelids 201, 202 of the user in the present disclosure is notlimited thereto.

The circuit structure 3 arranged in the embedded module 10 can beindependently used (not shown in the drawings) or can be used incooperation with the electronic component 2, so that the circuitstructure 3 (and the electronic component) can be electrically orphysically driven to implement at least one of functions includingenergy reception, wireless signal transmission, digital calculation,sensing and monitoring, pressure application, current release, imageprojection, optical zoom, and power storage, but the present disclosureis not limited thereto.

As shown in FIG. 1 to FIG. 6 , the circuit structure 3 in the presentembodiment includes a carrier 31 and a circuit 32 (e.g., a metalliccircuit) formed on the carrier 31. The circuit 32 is connected to theelectronic component 2 to be electrically coupled to each other, but thepresent disclosure is not limited thereto. For example, as shown in FIG.7 to FIG. 9 , the circuit structure 3 can include a circuit 32 that isconnected to the electronic component 2 and that is not formed on anycarrier. In other words, the embedded module 10 of the presentembodiment can provide a pre-positioning function for the circuit 32through the front supporting ring 4 and the rear supporting ring 5,thereby preventing the circuit 32 in the manufacturing process of thelens body 1 from being moved or being deformed.

In the present embodiment, as shown in FIG. 1 to FIG. 6 , the carrier 31can be shaped to form a predetermined curved structure by being pressedfrom a mold at a normal temperature or a high temperature, so that thecarrier 31 has a fixed curvature that is different from the secondcurvature, and the fixed curvature is preferably close to thepredetermined curvature provided by the rear surface 1 b and the rearcurved surface 52 (e.g., the fixed curvature is 100% to 110% of thepredetermined curvature), but the present disclosure is not limitedthereto.

The carrier 31 in the present embodiment is a flexible printed circuitboard (FPCB) having a thickness within a range from 10 μm to 300 μm.Moreover, the thickness of the carrier 31 is preferably within a rangefrom 40 μm to 80 μm, and polymer materials of the carrier 31 can includepolyimide (PI), liquid-crystal polymer (LCP), polyethylene terephthalate(PET), or poly(ethylene 2,6-naphthalene dicarboxylate) (PEN), but thepresent disclosure is not limited thereto.

Specifically, the carrier 31 has a C-shaped segment 311 that is embeddedin the layout region 121 and a connection segment 312 that is embeddedin the lower eyelid region 122. The connection segment 312 is connectedin-between two distal ends of the C-shaped segment 311. The electroniccomponent 2 can be assembled to the connection segment 312, and thecircuit 32 is formed on the C-shaped segment 311 and extends to theconnection segment 312 for being electrically coupled to the electroniccomponent 2.

Moreover, since the carrier 31 easily wrinkles or has stressconcentration in a pressing and forming process, the C-shaped segment311 has at least one thru-hole 3111 that is fully filled with the lensbody 1 (e.g., the annular wearing portion 12). It should be noted that,in a top view of the contact lens 100 along (or perpendicular to) thecentral axis L, an area of the at least one thru-hole 3111 is 1% to 85%(e.g., preferably 10% to 40%) of an area surrounded by an outer contourof the C-shaped segment 311, thereby effectively reducing generation ofthe wrinkles or the stress concentration on the carrier 31, and furtherincreasing the oxygen permeability of the contact lens 100 by being incooperation with the free curved surface 12 a.

In addition, the carrier 31 can have a plurality of radial notches 313recessed from an outer edge thereof toward the central axis L so as toallow the carrier 31 to have a fixed curvature, thereby further reducingthe generation of wrinkles or the stress concentration on the carrier31. In the present embodiment, the radial notches 313 are fully filledwith the annular wearing portion 12, and the radial notches 313 arerespectively formed on boundaries between the C-shaped segment 311 andthe connection segment 312, but the present disclosure is not limitedthereto.

Moreover, in the top view of the contact lens 100, the area of the atleast one thru-hole 3111 is 1% to 75% of an area of the annular wearingportion 12. Moreover, a quantity of the at least one thru-hole 3111formed on the C-shaped segment 311 in the present embodiment is morethan one, but the present disclosure is not limited thereto. Forexample, in other embodiments of the present disclosure not shown in thedrawings, the C-shaped segment 311 of the carrier 31 can be formedwithout any thru-hole 3111.

In the present embodiment, the circuit 32 has at least one enclosedloop, and the thru-holes 3111 of the C-shaped segment 311 are arrangedin the at least one enclosed loop of the circuit 32. It should be notedthat a quantity of the at least one enclosed loop in the presentembodiment is more than one, and the thru-holes 3111 are respectivelyarranged in the enclosed loops of the circuit 32, but the presentdisclosure is not limited thereto.

Each of the thru-holes 3111 is curved and has a width that graduallyincreases from two ends thereof toward a center thereof (e.g., thethru-hole 3111 in the present embodiment is substantially in a crescentshape). Specifically, any one of the thru-holes 3111 has an inner edge3112 and an outer edge 3113, and two ends of the inner edge 3112 arerespectively connected to two ends of the outer edge 3113 so as to formthe two ends of the thru-hole 3111.

Any one of the inner edge 3112 and the outer edge 3113 is in an arcedshape, a radius of the inner edge 3112 is less than a radius of theouter edge 3113, and a center of the inner edge 3112 and a center of theouter edge 3113 are respectively located on two different planesperpendicular to the central axis L. In other words, each of thethru-holes 3111 in the present embodiment is arranged along the fixedcurvature of the carrier 31 and is not located on a flat plane.

In order to clearly describe the arrangement of the thru-holes 3111, thefollowing relationships are described according to the top view of thecontact lens 100. The central axis L defines an origin point, an X axis,and a Y axis that is perpendicular to the X axis, and the X axis and theY axis are intersected at the origin point. The contact lens 100 issequentially divided into a first quadrant Q1, a second quadrant Q2, athird quadrant Q3, and a fourth quadrant Q4 along a counterclockwisedirection with respect to the origin point.

In the top view of the contact lens 100, the lower eyelid region 122 isarranged in the third quadrant Q3 and the fourth quadrant Q4, the Y axisis substantially a center line of the lower eyelid region 122, and acentral angle 6122 of the lower eyelid region 122 with respect to theorigin point is preferably within a range from 30 degrees to 180degrees. The central angle 6122 can be changed according to designrequirements and is not limited by the present embodiment.

Moreover, in the top view of the contact lens 100, the thru-holes 3111are arranged in the first quadrant Q1, the second quadrant Q2, the thirdquadrant Q3, and the fourth quadrant Q4 (e.g., four parts of thethru-holes 3111 are respectively arranged in the first quadrant Q1, thesecond quadrant Q2, the third quadrant Q3, and the fourth quadrant Q4),and an area of any one of the four parts of the thru-holes 3111 is 50%to 150% of an area of another one of the four parts of the thru-holes3111.

Specifically, in the top view of the contact lens 100, any one of thethru-holes 3111 is arranged across at least two quadrants (e.g., any oneof the thru-holes 3111 is arranged in the first quadrant Q1 and thefourth quadrant Q4, or is arranged in the second quadrant Q2 and thethird quadrant Q3), and any one of the thru-holes 3111 can be mirrorsymmetrical across the X axis, but the present disclosure is not limitedthereto.

The thru-holes 3111 include at least one first thru-hole 3111 a and atleast one second thru-hole 3111 b. Moreover, a quantity of the at leastone first thru-hole 3111 a and a quantity of the at least one secondthru-hole 3111 b in the present embodiment can each be more than one,but the present disclosure is not limited thereto. The first thru-holes3111 a are located at an inner side of the second thru-holes 3111 b. Inother words, a radius of each of the second thru-holes 3111 b isdifferent from (e.g., greater than) a radius of each of the firstthru-holes 3111 a.

In the present embodiment, each of the first thru-holes 3111 a is in anarced shape having a center of circle located on the central axis L, andthe first thru-holes 3111 a are spaced apart from each other. Each ofthe second thru-holes 3111 b is in an arced shape having a center ofcircle located on the central axis L, and the second thru-holes 3111 bare spaced apart from each other.

Moreover, any one of the first thru-holes 3111 a is located in a regiondefined by a central angle of the corresponding second thru-hole 3111 b,and a partition between any two of the first thru-holes 3111 a adjacentto each other and a partition between any two of the second thru-holes3111 b adjacent to each other are not arranged in a same radialdirection of the contact lens 100.

It should be noted that the contact lens 100 in the present embodimentcan be further cooperated with any type of device. For example, in otherembodiments of the present disclosure not shown in the drawings, thecontact lens 100 can be wirelessly connected to any wearable device(e.g., a glasses-mounted reader or a neck-worn reader) worn on a user,and the wearable device (or the reader) can use a common wirelesstransmission technology (e.g., the RFID technology in a bandwidth of13.56 MHz or 860-960 MHz) or other wireless technologies of inductionpower or signal transmission so as to supply power, sensing function, orsignal feedback for the contact lens 100, thereby providing anintelligent monitoring (e.g., a full-time intraocular pressure valuecollection and warning), an intelligent treatment (e.g., a dry-eye drugsustained release control), AR services (e.g., an image projection), orother intelligent applications.
